rasp canes - heel in?

I received a bunch of 5 autumn bliss bare root canes today.  Trouble is, I wont be able to plant out until a week on Saturday, (9 days).  Ive just been out in the dark and heeled them in.  Will they be ok until then?  Not sure how quickly the roots will start to develop and take hold.  Beginning to think I should have separated the bunch 

Ace, thanks.  Unlikely to dry out here - been raining solid for 2 days 

I read I should cut them down to 20cm after planting.  They are probably about 35-40cm at the moment with some nice healthy looking buds.  Would you cut them down further  after planting in final spot?

I would cut them back to one or two buds. This will allow some early leaf growth so the canes can gain strength to grow new canes

Autumn Bliss fruit on the current years growth. This means come spring they will send up new shoots to fruit later in the year, and once the fruit is over you cut them back to ground level. Spring and summer fruiting varieties however fruit on the previous years growth, so after fruiting you only cut out the 'woody stems', (which should be tied to supports) and leave the soft green ones. Easy to then tie them in so you know which ones to cut back next year.
